Periodic Solutions in Shifts for a Nonlinear Dynamic Equation on Time Scales

Erbil Çetin, F. Serap Topal
2012 Abstract and Applied Analysis  
Let be a periodic time scale in shifts . We use a fixed point theorem due to Krasnosel'skiĭ to show that nonlinear delay in dynamic equations of the form , has a periodic solution in shifts . We extend and unify periodic differential, difference, -difference, and -difference equations and more by a new periodicity concept on time scales.
